摘要： PURPOSE:To provide a lightweight lattice like structure hard to rust and capable of being produced inexpensively. CONSTITUTION:Rows of longitudinal and lateral materials 2, 3 consisting of metal core materials 2a, 3a and coatings 2b, 3b made of a thermoplastic resin having a high dielectric loss factor are superposed one upon another in a lattice form and both surfaces of the superposed one are held between a pair of pressure plates under pressure and high frequency voltage is applied across the core materials 2a, 3a to subject the longitudinal and laterial materials to high frequency welding so that the crossing parts 4 of the coatings 2b, 3b are engaged to constitute a lattice like structure 1. By this method, the lattice like structure 1 made of a synthetic resin-metal composite having high strength and a clean welded parts is obtained.

摘要： PURPOSE:To inexpensively produce a lightweight lattice like structure hard to rust having rows of longitudinal materials made of a thermoplastic resin having a high dielectric loss factor and rows of lateral materials made of the same resin and crossing the longitudinal materials and specifying the contact rate and peel strength of the crossing part of the longitudinal and lateral materials. CONSTITUTION:A lattice like structure 1 consists of rows of parallelly arranged longitudinal materials 2 made of a thermoplastic resin or rubber having a high dielectric loss factor and rows of lateral materials 3 made of the same resin or rubber and crossing the longitudinal material 2 at a right angle on the upper surface side of the longitudinal materials 2. The rows of the longitudinal materials 2 and the rows of the lateral materials are engaged at the crossing parts 4 thereof at a contact rate of 10-40% and the peel strength of crossing parts 4 is set to 10% or more the tensile strength of the materials low in tensile strength among the longitudinal and lateral materials 2, 3. Both surfaces of the structure wherein the rows of the lateral materials 3 are superposed on the rows of the longitudinal materials 2 are held between a pair of electrode plates under pressure and subjected to high frequency welding so that the crossing parts 4 are engaged to form the lattice like structure 1.
