CORE MATCORE MAT CLASS A: is also offered with 3 layers ,2 of fiber glass and 1 with polypropylene, and the standard materials are: SPECIFICATION Glass Fiber g/m2 Total dry weight g/m2 HLA 300C300 600 780 HLA 450C450 950 1130 HLA 600C600 1200 1380 HLA 300D300 600 850 HLA 450D450 950 1200 HLA 600D600 1200 1450 CORE MAT is also offered with 2 layers, 1 of fiber glass and 1 with polypropylene, and the standard materials are: SPECIFICATION Glass Fiber g/m2 Total dry weight g/m2 HLA 300C 300 480 HLA 450C 450 630 HLA 600C 600 780 HLA 300D 300 550 HLA 450D 450 700 HLA 600D 600 850 How to understand CORE MAT CLASS A description: Example: HL200B200B200 Layer 1: 200g/m2 of glass fiber Layer 2: Synthetic material Layer 3: 200g/m2 of glass fiber Layer 4: Synthetic material Layer 5: 200g/m2 of glass fiber As you can see the number refers to the glass fiber areal weight in grams per square meter. Regarding the synthetic core 4 options are available: A: 90g/m2 B: 125g/m2 C: 180g/m2 D: 250g/m2 Comparing C and D we can say that for the same glass content and the same mould C option provides better resin flow, but the mechanical properties are slightly worse because the ratio glass/resin is lower. CLASS A refers to the surfacing veil made with PAN fibers.The areal weight of this veil is 70 g/m2
