摘要： A method of non-destructive inspection for resinous automotive bumper beams provides for applying a flexural load to the center of a bumper beam by a pressing jig in a state where both ends of the bumper beam have been pivotably supported to gradually bend the bumper beam, measuring or determining the bending strain and energy absorption of the bumper beam upon the application of the flexural load, said energy absorption being calculated from said bending strain and flexural load, and judging the bumper beam to be good in quality only when the energy absorption of the bumper beam reaches at least a control value of the energy absorption, which is set up in advance, in a state that the bending strain of the bumper beam is at most a control value of the bending strain, which is set up in advance. The control value of the energy absorption is determined by correcting the value of energy absorption upon destruction of a bumper beam, which has been found in a standard destructive test. The control value of the bending strain is determined by correcting the bending strain in the standard destructive test. These corrections are performed on the basis of the correlations between a plurality of data as to the energy absorption and bending strain in the standard destructive test and a trial destructive test, respectively.
摘要翻译：用于树脂型汽车保险杠梁的无损检测方法提供了在保险杠梁的两端已被可枢转地支撑以逐渐弯曲保险杠梁的状态下通过加压夹具将弯曲载荷施加到保险杠梁的中心，在施加弯曲载荷时测量或确定缓冲梁的弯曲应变和能量吸收，所述能量吸收由所述弯曲应变和弯曲载荷计算，并且仅当所述缓冲梁的能量吸收在保险杠的弯曲应变至多为预先设定的弯曲应变的控制值的状态下，保险杠至少达到预先设定的能量吸收的控制值。能量吸收的控制值通过在标准破坏性试验中发现的修正缓冲梁破坏时的能量吸收值来确定。通过校正标准破坏性试验中的弯曲应变来确定弯曲应变的控制值。这些校正是基于标准破坏性试验中的能量吸收和弯曲应变的多个数据与试验破坏性试验之间的相关性进行的。

摘要： A plurality of thermoplastic sheets are laminated into a laminated assembly, which is then pressed into a laminated assembly. First, the sheets to be laminated in one cycle are heated while the sheets are arranged in a juxtaposed relationship in the order in which they are to be laminated. The heated sheets are penetrated with needles to detachably hold the sheets while keeping the sheets in the juxtaposed relationship. A support member which supports the laminated assembly is moved below the sheets held and relatively to the sheets in a direction in which the sheets are arranged in the juxtaposed relationship, the sheets are released from the needles onto the support member to stack the sheets thereon into the laminated assembly while the support member is being moved relatively to the sheets. The support is then delivered into a shaping die assembly. The laminated assembly on the support member which has been delivered into the shaping die assembly is charged into a charging position in the shaping die assembly, and the support member is removed from the shaping die assembly. The laminated assembly is then pressed into a shaped product with the shaping die assembly after the laminated assembly has been charged into the charging position.

摘要： An automobile bumper comprises a bumper face and a bumper beam constructed of members molded of thermoplastic resin. The bumper beam includes at least two members of thermoplastic resin having flanges for forming beam flanges together when the members are fused to each other, the beam flanges being fused to an inner surface of the bumper face. An FRP sheet is continuously heated in an atmosphere having a temperature successively lowered from a temperature higher than a resin melting temperature at which a resin of the FRP sheet is melted so that the entire FRP sheet is increased through successive heating stages to a temperature between the resin melting temperature and a resin degradation temperature at which the resin of the FRP sheet is degraded. Heaters are brought into close proximity with joining surfaces to be fused of at least two parts of synthetic resin with a prescribed spacing therebetween for melting the joining surfaces, and thereafter the melted joining surfaces are pressed against each other to fuse the parts together. At least one of the at least two parts comprises an FRP product made of glass fibers reinforced with a thermoplastic resin, the joining surfaces of the FRP product having a plurality of projections containing the thermoplastic resin only, the projections being melted when the parts are fused together.
